Two new species of spotted Hypancistrus from the Rio Negro drainage

Abstract
Two new species, Hypancistrus phantasma and Hypancistrus margaritatus, are described based on material from the Rio Negro drainage. Both species are distinguished from congeners by unique color patterns. Hypancistrus phantasma is described from the Rio Uaupes and differs from congeners by having a tan body with small dark spots (vs. dark with light spots or with saddles or stripes). Hypancistrus margaritatus is described from the Takutu River and differs from congeners by having densely-packed light spots on a dark brown background, with spots about the size of the nasal aperture (vs. sparse light spots either smaller or larger than the nasal aperture, or brown to black spots, saddles, or stripes).

Thanks Milton. Nicely done.

So do you predict that is H. margaritatus?

Cheers, Eric

Wow, so Hypancistrus phantasma is a kind of big L174?

Thanks! Yes, I am pretty sure H. margaritatus is L404.

That's one way to put it. I would describe it more as a Hypancistrus inspector with inverted colors.

Is it therefore appropriate to make L404 a synonym of H. margaritatus? I'll do that if you think it's correct.]

I assume you mean assign L404 as a common name? IIRC that's what PC normally does for retired L-numbers. I think that it's probably correct.
